ESU LokSound 5 DCC 21 Pin



The ESU LokSound 5 DCC 21 pin is the most important and advanced member of the LokSound family, boasting a huge 128Mbit of sound memory, with a class D audio amplifier outputting 3W, 16 Bit, 31.25kHz Hi-Fi quality sound. Speakers with an impedance between 4-32 Ohms may be used, or simply use the supplied standard 11 x 15mm sugar cube speaker and customisable enclosure. With an overall size of 30 x 15.5 x 5.5mm the LokSound 5 will fit into almost any H0 or 0 scale locomotive.

Available in 21 pin and 8 pin configurations. Simply cut of the 8 pin plug for hardwire applications.

This decoder can be loaded with any ESU sound project of your choosing for a small extra cost, select the appropriate drop down menu option for this option. Click this link to access the ESU sound file database. A wide range of sound files from North America/Australia and Europe are available.

Alternatively you can purchase an ESU LokProgrammer to load your own sound files and make adjustments to your decoder, however please note that CV changes can still be done with all good DCC systems. Contact us if you are interested in purchasing a LokProgrammer.
